Marshall amp serial numbers dating amps
However the dates for these batches are certain to be later than the batch shown immediately above, or earlier than the batch shown below.
If you've got an amp in this category and can supply any of those codes as well as the serial number, I would Also, things got a little crazy during Fender's last few months in the Fullerton factory, and when the management buyout was complete (March 1985) they had some parts but no factory.
